Thanks all! Here is another trace based on a better angle straight-on side view from one of the F30 video. The first spy shot had partial skewed from camera perspective. Instead of tracing camo lights, I applied design cues from F01 and F10. The final design is yet to be seen.

Great capture and sketchup Mii. A lot of attention to detail. They clearly seem to be moving to more of the sharknose style of the Z4 while increasing the wheelbase and bulking up the boot. Given the other current styling trends, I also wouldn't be a bit surprised to still see more curves or creases. I like that the 3's are getting a little less sterile, but I hope they don't go over the top with the sculpting. Although the newer Z4 styling shows a little more aggressiveness, I liked the simplicity of the previous sheet metal.

I agree with BMW16, the E46 is a much nicer looking car than the E90. They need to make the F30 look lower and wider and fix the awkward looking head and tail lights of the E90. The trace seems to do that, great work Mii. I'm sure Adrian will weave his magic and not disappoint.

^Under BMW new module platform, F30 3er is sharing platform among new Z4, 3er GT, and X3. We may get idea of design language and element from F25 X3 such as creases, curves, etc. Though each model will remain unique to each own with details. For example, F01 7er, F07 5er GT, and the new F10 5er are all under common platform with different look on each own while sharing similar design elements. According to BMW insider, the best place to locate camouflage off X3 will be in Spartanburg, by then we can get a closer look of the new X3 design detail.

^^Based on tire diameter scaling on side view profile of the video shot.

Estimate dimension of F30: (+/- 0.6% (0.006) margin of error)

Height: 55.8"
Length: 178.7"
Wheelbase: 110.2"

Boy, I hope these numbers are correct (or as you suggest, very close). Just about every pub I have read is predicting a longer, wider F30 compared to the E90. BMW has gone "bigger" consistently over the past few model cycles, especially the 5er. Given the upcoming CAFE increases, it seems bizarre that so many car companies are going bigger/heavier, even if they are down-sizing engines.
Let's hope that BMW not only holds the line on size but also gets some of the weight out of the 3er.
